Thanks for your reply.

Well, I've already tried those devices. I've read the man pages on everything I
could find using apropos, so I have a reasonable understanding of the
significance of the device naming conventions. As a desperate measure, I even
wrote a script to tip(1) to all the likely devices in /dev, but to no avail.

Interestingly, I installed the same distribution (bindist.?? from DOS floppies)
on a 386SX, and had the same problem. I've used tip, echo and cat. From memory,
I think echo and cat also claim that the port cannot be opened.

It may be significant that the laptop has a PCI architecture.

Regards,
Casper.
